To make the most of RF systems often it is important to amplify a signal, or filter out noise from other systems so the radio equipment can perform at the locations required with an acceptable signal to noise margin.

STI Engineering has developed a low-powered Remote Irrigation Controller (RIC) in collaboration with Greenspan-MCE. The unit is built on the successful Piccolo platform, offering reliable communications in the 433 MHz license-free band.

The RFI-433 RIC was recently installed in an 80-site irrigation and pump start system in Emerald, QLD.
